The name Cepolidae Ihering, 1909 is a homonym for the family Cepolidae Rafinesque, 1815 (based on Cepola Linnaeus, 1766 ) a family of bandfishes in the superfamily Cepoloidea within the order Perciformes. The name of the gastropod family needs be submitted to the International Commission on Zoological Nomenclature to resolve the homonymy.
